MOTOR-GEAR.

SPECIFICATION forming part of Letters Patent 1Y0. 7 59,609, dated May10, 1904.

Application filed December 21, 1903. Serial No. 186,112. (No model.)

To all whom it may concern:

Be it known that I, J osnrn HAVLUJ, a citizen of the United States,residing at Luther, in the county of Oklahoma and Territory of Oklahoma,have invented certain new and useful Improvements in Motor-Gear; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention is an improved motor-gear for operating light machinery bymanual power; and it consists in the construction and combination ofdevices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of amotor-gear embodying my improvements. Fig. 2 is a transverse sectionalview of the same taken on the plane indicated by the line a a of Fig. 1.

1n the embodiment of my invention here shown I provide a frame or casing1, which comprises a base 2, a pair of oppositely-disposed sides 8 andcross-bars 4, which connect the sides together and are located atsuitable distances from their upper and lower ends.

In suitable bearings in the sides 3 is journaled a driving-shaft 5. Onthe said shaft are a pair of spur-gears 6, which are revolubleindependently thereof, and a pair of ratchetwheels 7, which are fast tosaid shaft. The said spur-gears and ratchet-wheels are closelyassociated, and each of the ratchet-wheels is on one side of one of thespur-gears. The latter are provided with spring-pawls 8, which engagethe ratchet-wheels.

Peripherally-grooved guide-rollers 9 are mounted on the inner sides ofthe cross-bars 4, as shown, and serve to guide the verticallydisposedrack-bars 10 of a reciprocating racklink 11. Each of these rack-barsengages one side of one of the spur-gears. Hence at each stroke of therack-link the spui' gears, which are loose on the shaft 5, will besimultaneously reversely rotated. The pawl of one of the wheel.

operation the shaft will be rotated in one direction only.

The hand-lever 12 is pivotally mounted on brackets 13, which projectfrom one side of the frame or casing at the upper end thereof, and thesaid hand-lever has its inner end connected to the reciprocatingrack-link by a pitman 14 or other suitable device.

Power may be conveyed from the drivingshaft to the machine to beoperated by the motor-gear by any suitable means. 1 here show in Fig. 2a spur-gear 15 on one end of the driving-shaft for this purpose. Apulley for driving a belt may be substituted, as will be understood, orany other suitable device may be employed in lieu thereof. I do notlimit myself in this particular.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A motor-gear comprising a frame having peripherally groovedguide-rollers mounted at the sides thereof, a rack-link having itsrackbars engaging said grooved guide-rollers, a lever, a link connectingthe latter to the racklink, spur-gears engaging the respective rackbarsof the rack-link, a shaft on which said gears are loosely mounted andhaving its bearings in the frame, ratchet-wheels fast to said shaft, andpawls carried by the respective spur-gears and coacting with therespective ratchet-wheels to revolve the shaft in one direction whenreciprocating movement is imparted to the rack-link by the lever.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
